My Acer desktop pc has 3 usb ports at the front and 4 at the back of the tower. over recent weeks when anything is plugged into the front, I get constant connect/disconnect sounds, as the pc is quite old now I put this down to age and that the ports no longer had a snug fit and I did use the front ports quite often.
I bought a four hub usb connector and plugged this into one of the rear ports. Now whenever I plug in a usb stick or the mobile phone or tablet am still getting the disconnect/connect sounds, it's like it's cutting out, however, can't be the ports because I have a usb mouse and keyboard plugged into the back and have no problems with them. The back ports are not used due to access. I've checked in device drivers and uninstalled the drivers and reloaded them, any ideas?
